Bonfire: Check for Palindromes Difficulty: Level 1

Return true if the given string is a palindrome. Otherwise, return false.

 palindrome is a word or sentence that’s spelled the same way both forward and backward, ignoring punctuation, case, and spacing.

You’ll need to remove punctuation and turn everything lower case in order to check for palindromes.

We’ll pass strings with varying formats, such as “racecar”, “RaceCar”, and “race CAR” among others.

Here are some helpful links:


My solution:

function palindrome(str) {

//delete global spaces
var nospace = str.replace(/\s+/g,”);
var nospace = str.replace(/\W+/g,”);

//replace nospace with lowercase letters
var newstring = nospace.replace(/[A-Za-z]g,/).toLowerCase();

//reverse the string without spaces
revstr = nospace.split(”).reverse().join(”).toLowerCase();

//test original string w/o spaces to reversed string w/o //spaces
if (newstring === revstr)
return true;
else {
return false;

palindrome(“A man, a plan, a canal. Panama”);
